We dont require it. Nor did my previous company. I thought it was crazy at first, but, with both companies, the properties I was on had extremely low delinquencies. I questioned why we didn't and the response made perfect sense... If they pass the credit check, they obviously know how to manage their money. Why do we need to question them for proof? Additionally, we don't tell people we aren't going to ask for verification. So they most likely will put in an accurate amount.
